CON ERTIBLE DUMB-BELL.

Specification of Letters Patent. I

Patented Oct. 13, 1914.

Application filed February 26, 1914. Serial No. 821,184.

To all whom it may concern: Be it known that I, ANTHONY J. LATELLA, acitizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Convertible Dumb'Bell, of which thefollowing is a full, clear, and exact de-1 scription. i i This inventionrelates to a dumb-bell of the convertible type, that is to say, it canbe converted from an elastic or yielding dumbbell to one resembling asolidjdumb-bell, the weights of which are adjustable, whereby thearticle is of universal application.

The invention has for its general objects; to provide a comparativelysimple and in expensive dumb-bell of the character referred to which isreadily changeable from one type to the other as to weight.

Another obj vision of a dumb-bell which is split longitudinally and hasa removable middle section to the ends ofwhich are applied adjustableweights, such middlesection being removable for permitting thesidesections of the handle bars to be used in connection with one or moresprings which convert the article from a solid to a yielding handledumb-bell. I Y

A further object of the invention is the provision of simple, effectiveand novel means for uniting the parts of the dumb-bell adjustably anddetachably together.

With such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention and wherein similar characters of reference indicatecorresponding parts in all the views, Figure 1 is a plan view of thearticle shown as a solid bar dumb-bell; Fig. 2 is a perspective viewshowing the parts of the dumb-bell separated to illustrate the detailsof construction and with the weights removed; Fig. 3 is a sectional viewof one end of the dumb-bell; and Fig. 4 is a perspective view showingthe dumb-bell as of 5 the elastic or compressible bar type.

and easily adjustable; p 1 the middle section C areformed with spin ectof the invention isthe pro- Referring to the drawing, A and B designatethe two main sections of the dumbbell, the middle part of the saidsections being rounded to form a grip bar 1 and heads or balls 2 areformed on the ends of the portions 1. Disposed between the sections Aand B is a middle sec sections, thepins having countersunk heads 4 inthe section A, and thesection B has set screws 5 which are threaded inopenings 6 in the end faces of the headextremities 2 of the section B,such set-screws having theirinner ends frictionally engaged with theconnecting pins 3. The extremities of dles Twhich serve to receive aplurality of disks or other elements 8 of different sizes and weights,and these disks are held in collars 9 will be shifted inwardly so as toclamp the weights tightly against the main body of the dumb-bell andthus prevent looseness and rattling.

When the dumb-bell is to be converted bar, the middle section C isremoved entirely from between the sections A and B, and helicalcompression springs 11 are interposed between the sections A and B, asclearly shown in Fig. 4c. The opposed faces of the sections A and B haveseats or sockets v12 for receiving the ends of the springs, theoutersprings being held in place by the connecting pins or fastenings 8.Obviously the number of springs can be varied according to theresistance desired, the maximum resistance being afforded by the sevensprings shown in Fig. 4:. The intermediate springs can be removed if alighter resistance is desired. The pins 3 pass loosely through the endsof the section A, so that when the two sections A and B are compressedtogether, the' section vA will slide on the pins or fastening elements3. The pins 3 in this form or dumb-bell are longer than the pinsrequired for the type shown in Fig. 1. a

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation willbe readily under stood by those skilled" in the art to which theinvention appertains, and while I have described the article which I nowconsider to be the best embodiment thereof, I de-. sire to have itunderstood that the article shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the appendedclaims. Having thus described my invention, I claim as new and desire tosecure by Iietters Patent:

"1. A dumb-bell divided longitudinally into three sections, adjustableweights on the extremities of the middle section, and ,means for'removably securing the outer sec- 25, tions to the middle section andpermitting the outer sections to be detached while the weights remain onthe inner section, said outer sections being located between the saidweights.

'2. A dumb-bell divided longitudinally into three sections, adjustableweights on the extremities of the middle section, and: means forremovably securing the outer sections to the middle section andpermitting the outer sections to be detached while the weights remain onthe inner section, said 'outer sections being located between the saidweights and having seats .on their inner surface to receive springswhereby the dumb-bell is convertible from a solid handle to resilienthandle device.

3. A dumb-bell having a grip portion and weight enlargements at itsends, and said dumb-bell being divisible in two parallel planes atopposite sides of the center to form a central and two outer sections,spindles extending axially from the ends of the middle sections,adjustable weights on the spindles, and means for removably fasteningthe outer sections to opposite sides of the middle section andpermitting the outer sections to be removed while the weights remain onthe spindles.

4. A dumb-bell having a grip portion and weight enlargements at itsends, and said dumb-bell being divisible in two parallel planes atopposite sides or the center to form a central and two outer sections,spindles extending axially from the ends of the middle section,adjustable weights on the spindles, and means for removably fasteningthe outer sections to opposite sides of the middle section andpermitting the outer sections to be removed while the weights remain onthe spindles, the inner surfaces of the outer sections being formed withseats for receiving springs whereby the dumb-bell can be converted intoa solid or yielding grip device.'

In' testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
